HAIR ROLLER Filed March 22. 1961 FIGB INVENTOR. E.W. SCH RODER UnitedStates Patent Ofifi ce 3 2 522 Patented Nov. 30, 1965 3,220,422 HAIRROLLER Ernest Wiliiam Schroder, 117 Bluff Sh, Council Bluffs, Iowa FiledMar. 22, 1961, Ser. No. 97,529 2 Claims. (Cl. 132-40) This inventionrelates to hair curlers, and particularly perforated hollow rollers uponwhich hair is wrapped, and in particular an elongated cylinder having aperforated wall with triple arm rods slidable in the ends and havingknurled knobs on the outer ends with elongated inwardly extended springclips mounted on the knobs and arranged to slide, selectively, throughnotches in ends of the cylinder for storage, or over hair wrapped aroundthe cylinder for preventing unrolling of the curler, and therebyretaining the curler against the head with the hair wrapped thereon.

The purpose of this invention is to provide a hair roller having springclips for holding hair wrapped thereon in which the spring clips areactuated to nested positions within the roller for storage, and whereinthe clips are not separated from the roller.

With conventional hair curlers the hair is wrapped around the rolleruntil the roller engages the head, and, with all of the hair wrapped onthe roller a pin is placed through holes in the roller to prevent thehair unrolling, or a clip is attached to the roller and placed over thehair to retain the hair in a comparatively tight position upon theroller.

An operator in a beauty parlor places hundreds of such rollers on haireach day and every time a roller is in place it is necessary for theoperator to reach down and pickup .a pin or clip as she places it on aroller.

With this thought in mind this invention contemplates a hair curler inwhich spring clips for retaining the hair wrapped on a roller of thecurler remain permanently on the roller, thereby obviating the necessityof reaching down and picking up a pin or clip for each roller.

The object of this invention is, therefore, to provide a hair curler inwhich spring clips are actuated to storage 6 Another important object ofthe invention is to provide a hair roller in which the hair is retainedin curling position thereon by clips, and in which the parts areassembled and taken apart without screws, bolts, or other fasteningelements.

A further object of the invention is to provide a hair curling roller inwhich hair is retained rolled on the roller by spring clips carried byknobs at the ends of the roller and slidably mounted by rods extendedinto the roller in which both the roller and rods are perforated topermit circulation of air through the roller and also through hairrolled thereon.

It is yet another object of the invention to provide a hair curlingroller in which the hair is retained wrapped around the roller by springclips and in which means is provided for preventing accidentalseparation of the clips from the roller.

A still further object of the invention is to provide an improved haircurler in which hair is retained rolled on the roller and by springclips slidably mounted on the roller in which the curler is of simpleand economical construction.

Other and further objects and advantages of the present invention willbe apparent from the following detailed description drawings and claims,the scope of the invention not being limited to the drawings themselves,as the drawings are only for the purpose of illustrating a way in whichthe principles of the invention can be applied.

Other embodiments of the invention utilizing the same or equivalentprinciples may be used and structural changes may be made as desired bythose skilled in the art without departing from the present inventionand the purview of the appended claims.

In the drawings:

FIGURE 1 is a side elevational view of the improved hair roller with onepart broken away and parts shown in section, and with a spring clipholding knob at one end of the roller shown in an extended position indotted lines.

FIGURE 2 is a cross section through the hair roller taken on line 22 ofFIGURE 1.

FIGURE 3 is a cross section through the roller taken on line 33 ofFIGURE 1.

While one embodiment of the invention is illustrated in theabove-referred-to drawings, it is to be understood that they are merelyfor the purpose of illustration and that various changes in constructionmay be resorted to in the course of manufacture in order that theinvention may be utilized to the best advantage according tocircumstances which may arise, without in any manner departing from thespirit and intention of the invention, which is to be limited only inaccordance with the appended claims. And while there is stated theprimary field of utility of the invention it remains obvious that it maybe employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, thesame reference characters are used to designate the same parts andelements throughout, and in which the numeral It) refers to theinvention in its entirety, numeral 12 indicating an elongated cylinderhaving perforations 14 therein, numerals 16 and 18 indicating springclips mounted in knobs 20 and 22, respectively, numerals 24 and 26 rods,Y-shaped in cross section, extended inwardly from the knobs, andnumerals 28 and 30 oval-shaped heads positioned on outer ends of therods and designed to engage inturned flanges 32 on inner ends of thecylinder 12 to prevent accidental separation of the spring clipassemblies from the cylinders.

Each knob 20, or 22, together with its respective rod 26 and itsrespective head 28, or 30, can be termed a clip carrying member 35. Eachclip carrying member 35 has an outer portion, which is its knob 20, or22, and an inner portion, which is the remainder of the clip carryingmember.

The inturned flanges 32 have central holes therethrough, which arepreferably cylindrical and are concentrically disposed with respect tothe axis of the cylinder 12.

Each clip carrying member 35 has a bearing portion 33, which is receivedwithin the respective end of the cylinder 12, each bearing portion 33having an outer surface, these outer surfaces being preferablycylindrical and shaped complementarily to the inner surface of the holethrough the respective inturned collar 32, as best shown in FIGURES 1and 2, whereby the cylindrical bearing surfaces 33 bear against thesubstantially cylindrical inner surfaces of the inturned collars or stopmembers 32, for rotation with respect thereto and in abuttingengagement.

As the outer surface of each bearing portion 33 is preferablycylindrical and disposed longitudinally parallel to the axis of thecylinder 12, it bears against and is guided by the hole through therespective inturned flange on the cylinder. It will thus be seen thatthe abutting surface of the bearing portion 33 and the hole through.therespective inturned flange 32 are cooperatively shaped for guiding thebearing portion to be rotated in a circular motion about the axis of thecylinder 12.

The inturned flanges 32 are provided with notches 34 through which thespring clips 16 and 18 extend in the nesting or storage positions, suchas indicated by the dotted lines 36; and by drawing the knobs 20 and 22outwardly, as indicated by the dotted lines 38, the rolled ends 40 and42 of the clips may be inserted in the cylinder through the notches, orwithdrawn from the cylinder for sliding over hair on the roller. Thespring clips are mounted on the curler by inner end portions of theclips, also called right angularly disposed ends, 44 which are embeddedin the knobs 20 and 22, the remainder of each clip being called itsouter portion the latter terminating in its outwardly rolled terminalend 40 or 42.

The outwardly rolled terminal ends 40 and 42 cause that surface of theterminal end which is adjacent to the cylinder 12 to be beveled and toincline outwardly toward the terminal end so as to ride up over rolledhair in use, as is common with hair clips. However, the spring clips maybe mounted on the knobs or rod by other means.

The webs of the rods 24 and 26 are formed with perforations 46 tofacilitate circulation of air through the roller and hair rolledthereon, and the heads 28 and 30 on inner ends of the cores are ovalshaped to facilitate forcing the heads through the inturned flanges 32on the inner ends of the cylinder. The parts of the curler are made of aplastic having sufficient resiliency to permit the heads 28 and 30 to beforced through the collars, and after the heads are through the inturnedflanges, out ward travel of the rods, knobs and clips is limited byengagement of the heads with the collars.

It will be seen that the cylinder 12 can also be called a roller 12 andthe roller 12 and the knob 22 are relatively movable with respect toeach other and can, therefore, together be called a relatively movableassembly made up of cylinder 12 and knob 22. The relatively movableassembly has a portion which is adjacent the flange or collar 32 attimes when a clip 16 or 18 is in the storage position, the said portionhaving a clip recess therein. The clip recess is identified in FIGURE 1as that part of the opening 34 which extends through. the side wall ofthe cylinder 12. The clip recess is in communication with the opening inthe flange 32 during clip storage. Each clip recess receives a portionof the respective clip 16 or 18 during clip storage. In this way, a cliprecess in a side wall cooperates with the opening 34 in the flange 32 topermit the knob to be moved inwardly more closely adjacent the cylinder12 than the clip position might otherwise allow.

It will be seen that end of each knob 20 or 22 which is disposedfarthest from the roller or cylinder 12 has an outer surface of a shapeat least sufficiently round as seen in cross section taken transverse tothe elongation of the roller as to facilitate rapid rolling of the knobin an operators fingers to rotate the knob for the positioning of therespective clip.

It will be seen that cylinder 12 can also be called a hollow elongatedroller having an outer side of substantially cylindrical shape. Thatpart of the knob 20 or 22 which extends inwardly of the respectiveflange 32 can be referred to as a concentric section on the inner faceof the knob adapted to be received in the passageway defined by theannular flange 32. Each head 28 or 30 is of such size and shape withrespect to the passageway defined by its annular flange 32 as tomaintain the respective head in the roller 12 during normal operation.

Operation In use the knobs are drawn outwardly until the ends of springclips 16 and 18 are in position to be inserted through the notches 34,and with the rolled ends 40 and 42 extended through the notches theknobs 20 and 22 are moved inwardly whereby the clips are positionedinside of the roller. The clips 16 and 18 are resilient so that theirouter portions are biased to move toward the central axis of thecylinder 14 and this facilitates the insertion of them into positionsinwardly of the cylinder 12. This also causes the clips to press towardthe outer side of the cylinder to firmly hold a hair roll, not shown, inplace.

With the clips in the roller, hair is rolled around the cylinder 12until the cylinder is against the head, and with the cylinder held inthis position, the clips are drawn outwardly by the knobs until therolled ends of the clips are in position to slide over the hair wrappedaround the roller.

By this means the rollers with hair wrapped thereon are retained againstthe scalp as the hair is dried by air circulated through the rollers andhair thereon.

It will be seen that the length of each clip carrying member 35, and thelength of that portion of the cylinder 12 in which the respective clipcarrying member is at times disposed, are such as to permit the freeterminal ends 40 and 42, respectively, of the clips to be disposedtoward the respective end of the cylinder, at which its respective knob20, or 22, is disposed, sufliciently so that the outer portion of therespective clip, including its terminal end 40, or 42, is substantiallyout of the way of the tress of hair, yet preferably on the cylinder 12,and these lengths are such as to permit the terminal ends 40 and 42, andthe outer portions of the clips, to be then moved across the cylinder 12axially of the latter, to respective positions alongside andsubstantially lapping the cylinder for holding a tress of hair (notshown) against the cylinder.

It will also be seen that the heads 28 and 30 have their diametersdisposed transversely of the cylinder 12, which diameter is greater thanthat of the central holes through the inturned flanges 32, whereby theheads 28 and 30 and the inturned flanges 32 serve as a means formaintaining the inner ends of the respective clip carrying member 35within the cylinder 12.

From the foregoing description, it is thought to be obvious that a haircurler constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof, and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice, except as claimed.
